ELECTRICAL ASSEMBLY & BUSBAR WORK
      • Revolution Slider Error: The param Slider Width should not be empty.
      • Fully modular design of LV switchboards

      • CRCA sheet punching on most modern CNC operated amada turret punch presses

      • Switch board members after punching bent on state of art CNC operated amada bending machines

      • Shell structural members sheared on shearing machine & punched on power press

      • All the components thoroughly inspected before sending for pre-treatment / powder coating
      • Revolution Slider Error: The param Slider Width should not be empty.
      • Material incoming receipt

      • Loading to pre-treatment basket

      • Pre-treatment carried in eight tanks using auto loader :

        • Degreasing in tank 1

        • Water rinse - 1 in tank 2

        • Derusting in tank 3

        • Water rinse - 2 in tank 4

        • Activation in tank 5

        • Phosphating in tank 6

        • Water rinse - 3 in tank 7

        • Passivation in tank 8

      • Water dried in a separate tank after pre-treatment

      • Pre treated items unloaded and inspected

      • Items loaded to an overhead powder coating conveyor, having a capacity of handling 15 tonnes of components per day

      • Powder spraying carried out in most modern automatic booth with robotic spray guns & powder recovery system of WAGNER, Germany, with a capacity of 15 tonnes of components per day

      • Powder is baked in a baking oven at 200 degrees centigrade, as the items move on the powder coating conveyor

      • The components are then inspected and despatched to shell assembly

      • Revolution Slider Error: The param Slider Width should not be empty.
